SAFETY INFORMATION
IT IS IMPORTANT TO COMPLETELY READ AND UNDERSTAND THE
INSTALLATION PROCEDURES BEFORE CONTINUING THE
INSTALLATION.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN
PROPERTY DAMAGE, SERIOUS BODILY INJURY, OR DEATH.
THIS PRODUCT SHOULD BE INSTALLED BY A LICENSED ELECTRICIAN
AND PLUMBER IN ACCORDANCE WITH ALL NATIONAL, STATE, AND
LOCAL ELECTRICAL & PLUMBING CODES.
Keep this manual in a convenient place for future reference.
DANGER! WATER TEMPERATURE
SAFETY SETTING
Safety is our primary goal when
selecting the water temperature.
Any temperature above 120°F can
cause serious scalding or death.
Energy conservation is a factor to
be considered when selecting the
water temperature. Setting the
water heater’s thermostat to a
lower setting will allow a higher flow
rate and use less energy.

INTRODUCTION
SioGreen Tankless hot water heaters do not store water like a conventional
tank-type water heater. It contains multiple high powered quartz heating tube
elements that are capable of heating water “on-demand” and continuously as
needed, so you will never have to worry about running out of hot water again.
The unit’s working principle and designs are simple. When the power is turned
on, the microprocessor will check the temperature sensor and current leakage
sensor, if there are no errors, the hot water generator is ready to work.
The performance of the products listed are dependent on incoming water
temp, water flow rate, and set temperature of the thermostat. In order for it
to function properly it must be matched by location, application, and unit size.
As it requires no venting, all units can be installed literally anywhere that is
convenient for the owner.
This product should be installed indoors only. An outdoor installation is
permitted as long as it is mounted in a suitable enclosure that protects it from
all-weather elements including freezing. Freezing of the unit may result in
permanent damage and will void the warranty.
Unit Operation:
When you open the hot water valve, the flow sensor activates at a minimum
water flow. The flow sensor sends the information to the temperature
controller to begin modulating the heating elements to heat the water as it
passes through the quartz heating tubes and to maximize efficiency.
If the water flow rate exceeds the maximum heating capacity of the unit, the
unit will reach a maximum achievable temperature based on flow rate and
unit size. When a reduction in the excessive flow rate is made, the unit will
achieve the set point temperature.
When the fixture is closed, the demand stops, the flow sensor sends
information to the controller to turn off the power to the quartz heating
elements. The unit remains in it standby mode until the demand for the hot
water is needed.

Unit Freezing:
In case of freezing, please wait for the complete defrosting of the unit before
using. Verify this by running water through it before turning on the power.
Activating unit while still frozen will damage the heaters internal components
and void the warranty.
Maintenance:
This unit requires no maintenance. To extend unit service life, it is
recommended to use an inlet pre filter or y-strainer, check, and clean it
periodically. This is an additional part from the internal screen included with
the unit. Do not attempt to open the case to make adjustments, repairs, or
for any reason. Opening of unit will void all warranties and could result in
serious injury or property damage.

MOUNTING YOUR WATER HEATER
1. Leave a minimum of 6” to both sides and 12” on the top and bottom of the
unit for clearance and maintenance. A minimum clearance of 24" in front
of the unit must be provided for safe removal of the front cover, for
installation, advanced troubleshooting, and service if required.
2. Mount the electric hot water generator securely to the wall with six (6)
screws. The two (2) mounting brackets located at the top and bottom of
the unit with eyelet holes.
3. This unit must only be mounted in a vertical position with the electrical and
water fittings located at the bottom of the unit.
4. Avoid installing the hot water generator in a corrosive environment, as this
may cause damage to the electronic components.
5. Installation of the hot water
generator must be in
accordance with all National
and Local codes having
Jurisdiction and installed by
a Licensed Contractor.

PLUMBING INSTALLATION
CAUTION: Breaker must remain off until installation is complete.
Step 1: Flush cold water line to clear any debris before connecting to unit.
Step 2: Install a shut off valve and pre filter (Not Supplied) to prevent any
particles entering the unit that may clog or damage the internal parts.
Step 3: Using flexible lines, connect the Cold Water line to the water heater
inlet labeled as “cold”. Connect furnished Water Valve to the water heater
outlet labeled as “hot”. Connect the HOT WATER outlet line to the Water Valve.
Step 4: Verify all fittings are tight and secure. Open hot water source and
allow water to run though the water heater for at least 1 to 2 minutes. This
will purge the air from the water lines and must be performed prior to turning
on the power at the unit. This is a Mandatory step to prevent Damage to
Heating Elements.
DO NOT solder any fittings to unit. This will damage internal sensors and
components and void the warranty. Use flexible lines and screw fittings only
to unit.
A TP valve is not required in most jurisdictions. Verify your local codes
accordingly and if required install on outlet side only.
Verify all connections are free of leaks.

SERIOUS
BODILY
INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.
SioGreen products must be installed by a licensed and qualified electrician in
accordance with all applicable national, state, and local electrical codes
depending on country.
Before installing this product, ensure that the home has sufficient electrical
power available to handle the maximum amperage load of the applicable
model.
IMPORTANT NOTES:
These units will require 2 sets of wire (see wiring diagram), 2 ground wires
and 2 breakers. Please see specifications by model and wiring diagram for
additional information.

Step 1: Remove cover of the water heater carefully and locate the electrical
disconnect breaker on the bottom left hand corner facing the unit.
Step 2: Use the correct wire gauge that meets all NEC or country of installation
guidelines based on the size of the breakers used to feed the unit and the
length of the wire run. Then run the set of wires from the home’s main panel
to the tankless water heater. (See above chart for minimum wire size) This
minimum wire size is based on maximum of 50’ of length.
Step 3: Take each wire pair and connect them to one breaker (see wiring
diagram). Make sure that each breaker is connected with one red wire and
one black wire.

Step 4: A separate ground conductor is required for each incoming circuit.
Step 5: Verify all connections are tight and secure. Verify the correct breaker
size. Verify the ground conductor size and connection per applicable codes.
CAUTION: Ensure that you have made the correct connections. You must
follow the wire connection as shown to ensure proper operation of the unit. If
you mix up one set of wires with another, the unit will not operate correctly
even though it turns on and otherwise appears to function properly.

How to calibrate your hot water using water valve
DANGER: Hotter water increases the potential for hot water SCALD
1. Make sure all electrical wires and water pipes are properly installed. Check
the power requirement for each model. Before start up, check that all
connections are secure and fittings are tight. Confirm that all air has been
purged from the system.
2. Turn power on and verify the unit set temp is 105-110 degrees. Open tub
faucet. The water begins to heat and the current temperature is shown in the
display. Dial the Gate Valve on the Hot Side Only to calibrate your hot water
vs the flow rate. Ideally, you will gain a higher flow rate by lowering the set
temp as water moves through the water heaters quartz elements faster. If
hotter water is required, simply raise the set temp and/or slow the water flow
rate to meet your temperature needs.
3. Calibrate using Gate Valve (water valve) at hot outlet and choose a
desirable temperature by pressing the up or down buttons and adjusting the
gate valve until you have a comfortable water temperature and flow rate.
Never use the cold inlet valve to adjust flow. This will restrict water from
flowing in and cause damage to the heating elements.
4. Turn off water and unit is set.
